ESCAPEIVIENT MECHANISM FOR I VIATBIX-ASSEMBLING MACHINES- SPECIFICATIONforming part of Letters Patent No. 791,131, dated May 30, 1905.

machines in which the matrices are stored in a plurality ofmagazine-channels.

The primary object of the invention is to provide novel escapementmechanism capable of being operated by associated finger-keys, wherebythe matrices will be released singly y from their several magazines.

Another object of the invention is .to lock all of the escapementmechanisms in operative positions, so that when the magazines areremoved and other magazines substituted the escapement mechanisms willall be in position to retain the matrices in the several magazines andto release them at will.

' The invention consists of the following mechanism associated with eachmagazine-- to wit, a freely-rotatable wheel having aplurality of teethwhich are capable of projecting one at a time into the associatedmagazine beneath the column of matrices therein and a pallet-leveroperable by a finger-key to permit a step-by-step movement of saidtoothed wheel.

It also consists of a bar adapted to be swung into engagement with allof said toothed wheels and to act in conjunction with the severalpallet-levers in preventing any movement of said toothed wheels.

In the drawings, Figure 1 is a sectional side elevation of that part ofa matrix-assembling machine which includes the present invention.

' Fig. 2 is a sectional side elevation of an esand therefore evidentlythe said channels might be formed in the frame member itself; but it isdesirable to be able to remove all themagazines from the machine,because thereby one may quickly substitute other magazines containingmatrices of a different style of type, and therefore the magazines are,as stated, formed in the removable plate '2. The plate 2, the loweredgeof which is suitably supported on a shelf 4, is secured to the framemember 3 by means of-a wedgearm 5, which engages with a strap 6 on therear side of the plate 2. This wedge-arm is secured to a shaft 7,mounted in hearings on the rear side of the frame member and in which itmay turn and move endwise. Y The spring 8 acts to move the shaft in thatdirection which will drive the wedge into said strap and which willresist its movement in the contrary direction. When the wedge-arm iswithdrawn by the endwise movement of the shaft, said shaft may beturned, the extent to which it may be so turned in either directionbeing limited by pins 9 9, secured to the frame member, between whichlies an arm 10, secured to said shaft.

A column ofmatrices 12 is stored in each one of these vertical magazines1, each matrix resting upon the one below it and the entire column beingsupported by one toothof a wheel 13, to be presently explained, whichprojects beneath the lowest matrix. Similar mechanism for supportingsaid matrix-col umns and for releasing only the lowest matrix in each isprovided for each of the matrix:

magazines, wherefore a description of one ofsuch mechanisms will answerfor all. An escapement-wheel 13, having four radiating; teeth 14:, 15,16, and 17 is loosely hung on a transverse axis behind its associatedmagazine, into which said teeth may project'oneat a time.

Specifically there is a transverse rod 18 secured to the framework ofthe machine, upon which all of the escapement-wheels 13 are looselymounted, as stated. Normally one of the teeth 14 on the escapement-wheelprojects into the magazine a short distance, and the lowest matrix restsupon it. The wheel is restrained from turning under the influence of theweight of the matrix-column resting upon said tooth by apallet-lever20,one arm, 21, of which engages with the tooth 17 of, theescapement-wheel. Another arm, 22, of this pallet-lever lies in such aposition that when the lever is rocked to withdraw arm 21 from itsengagement with the tooth 17 the arm 22 is brought into the path of saidtooth and engages therewith after the wheel has turned far enough topermit the lowest matrix to fall. Before it has reached this position,however, the tooth 15 of the wheel has passed beneath next to the lowestmatrix. The matrices are beveled off at their upper rear corner topermit their action. When the pallet-lever is rocked in the contrarydirection, it brings arm 21 into the path of the tooth 14 of the wheel13 and contemporaneously withdraws arm 22 from its engagement with thetooth 17, whereupon the weight of the column of matrices rotates saidwheel until further rotation is prevented by the engagement of the arm14: with the lever-arm 21,

The tail 23 of the pallet-lever projects into a notch 24 in avertically-movable bar 25, which is guided so that it must move in asubstantially vertical direction. The lower end of this bar rests uponthe rear end of one of the key-levers 26. It is clear, therefore, thatby depressing a key-lever the lowest matrix in the associated magazinewill be released and allowed to fall. This is all there is to theescapement proper and all that would be necessary if the magazines werenot formed as channels cut in the front face of a removable plate; butsince they are so formed, instead of being formed in the frame memberitself, it is desirable to have some means by which theescapement-wheels will be held in operative position when thismagazine-plate is removed and another magazine-plate is substituted. Ifthey are so held, they will be ready to perform their describedfunctions in connection with the matrices in the magazine of the plateso substituted. The means provided for so holding said escapement-wheelsconsists of a flat bar 27, pivoted to the frame member on an axisparallel with the axes of said escapement-wheels. Normally this baroccupies a position out of the range of the wheel-teeth. There isattached to this rocking-bar, however, an arm 28, the outer end of whichis pivoted to an upwardly-extending link 29, and the upper end of thislink embraces a crank-pin 30, attached to the shaft 7. When, therefore,this shaft has been moved endwise, so as to withdraw the wedge from thestrap 6 on the magazineplate, and is turned, as stated, the result willbe that this rocking bar will be moved so that it will ongage beneathone tooth on each of said escapement-wheels, (the tooth 16, as shown.)The pallet-levers will thereafter prevent said wheels from turning inone direction, while this bar will prevent them from turning in theother direction. In other words, they will be held stationary.

It will be understood that there is a plate 31, preferably of glass,which is secured across the front sides of said magazine-channels toclose them. When a plate 2 is about to be removed, a rod is passedthrough a hole in one edge of said plate, and under all of the matricesin all of the channels and then through a hole in the other side of saidplate. In this way the matrices are held in the magazines when the plateis removed.

The combination withamatrix-magazine channel, of a loosely-mounted wheel having teethadapted to project singly into said magazine-channel, and a pallet-leverfor controlling the turning of said wheel, a key-lever, avertically-movable rod supported upon said key-lever and. having a notchnear its upper end for the reception of the tail of said palletlever,substantially as specified.
